Even with the increased capacity and operating flexibility of NextGen, there will be situations and environments in which operators will compete for the same volume of airspace and airport facilities. Some may assume that contention for the same airspace in the future will be dealt with in a fashion similar to the methods in use today (e.g., controllers making tactical decisions to separate aircraft). However, under NextGen, trajectories or routes will be negotiated and contracted in advance with much greater accuracy and computers will be able to decongest the trajectories in advance. This means that, rather than controllers making tactical decisions on how to separate aircraft, computer algorithms will decide, within safety parameters, who goes first and who will have to wait, slow down, or take a different route. These Flight Prioritization (FP) rules in NextGen automation systems should be developed in a thoughtful way, considering what is best for aviation users and the National Airspace System (NAS). |
